エンドメトリオーシスによる尿管狭窄の1例

A 37-year-old woman was admitted to our hospital to examine left hydronephrosis. Retrograde pyelography showed left lower ureteral stricture. Abdominal CT scan revealed a tumor 1 cm in diameter in the left lower ureteral stricture. The diagnosis of left hydronephrosis and hydroureter due to left lower ureteral stricture was made, and left uretero-ureterostomy was performed. The histological findings revealed extrinsic type ureteral endometriosis. The present case, and the cases reported in the Japanese publications are reviewed.
